Apply
the Early Day Rules. This enables the change to the
fertile pattern of mucus to be recognized. Then postpone
intercourse until slippery mucus occurs. The next few
days are the most fertile. Therefore intercourse should
occur while slippery mucus is obvious.

2. For the Postponement of Pregnancy:

Apply

The Early Day Rules and

The Peak Rule

These rules are as follows.

The Early Day Rules:

Rule 1 - Avoid
intercourse on days of heavy bleeding during
menstruation.

Rule 2 - Alternate
evenings are available for intercourse when these days have
been recognized as infertile.

Rule 3 - Avoid intercourse on any day of mucus or bleeding which interrupts the Basic
Infertile Pattern. Allow three
days of Basic Infertile Pattern afterwards before intercourse is resumed.

The Peak Rule:

There must be avoidance of all genital
contact until the beginning of the fourth day following
the Peak (the
last day of a lubricative or slippery sensation at the
vulva ). From the fourth day until the end of the cycle intercourse is available every day at any time.

The daily chart is important:

in reminding a woman to pay
attention to the mucus sign every day;

giving valuable information to the
husband so that he and his wife can discuss the
possibilities.
